Onidel applies various default security settings, such as blocking outbound **RDP (TCP port 3389)** connections. This helps prevent malware-infected servers from being used in brute-force or DDoS attacks targeting other Windows systems on the internet.

If you have a legitimate need for outbound RDP traffic, you can easily disable the block:

1. Go to your **VM Management** page

2. Click the **Security** tab

3. Locate the option "**Block Outgoing RDP"**

4. Toggle the switch to **disable** the block

Once this setting is updated, your server will be able to initiate RDP connections to external systems.
